LCD TV Buying Guide

There are two compelling advantages with an LCD TV. The first is that they can be much easier to watch than a cathode ray tube (CRT) model. This is because screen displays are significantly brighter with a high contrast and the flicker free picture. LCD TVs will work effectively in almost any kind of room lighting from bright to ambient. Secondly, LCDs have a higher native resolution than plasma TVs of the same size making them ideal for high-definition output. While plasma TVs are currently better at the moment for sheer screen size, as more and more television output becomes high-definition TV (HDTV), LCD technology will come to the fore.

What is the purpose of LCD? Key Features and Accessories!
LCD technology is relatively complex and improving all the time but is based upon the fact that liquid crystals are, in their natural state, twisted. The ability of the crystals to allow light through can be altered by applying electric current. In smaller set will have aspect ratios of 4:3 although some models will have 16:9 widescreen display. In built sound is likely to be simple stereo, and refresh rates of 50Hz. These sets are typically available from between Rs.24,000 and Rs.44,000. In the case of the largest sets on the market prices can reach up to Rs.2,40000. At this level you can expect a feature rich set with a 16:9 screen, Dolby Virtual Surround Sound, refresh rates up to 100 Hz, and on some models additional decoders for HDTV and or Digital and terrestrial TV.

Key features:-

* Cheaper LCD sets may come with a passive matrix system. This has a grid of conductors with pixels located at each intersection in the grid. A current is sent across two conductors on the grid to control the light for any pixel. While this set-up will save you money you may notice the effects of the slow response time and less precise voltage control inherent in this arrangement. On screen you might see some ghosting and images which are fuzzy and lack contrast.

* Where LCDs really score over CRT models is in the physical depth of the television set. Most are less than 3" deep and can be hung on a wall or from a ceiling. This is a boon for those with smaller rooms or who want a release from the space-eating demands of a CRT.

* LCD TVs are particularly suited to act as a computer screen. Text and graphics will be made to look exceptionally sharp by their high-resolution. LCD TVs typically include connections for composite, S-video, component video and one or more RGB SCART inputs.

* Despite the slim line look, most LCD sets come with integrated tuners and speakers so there's no need to spoil the space-saving effect by cluttering up the room with additional boxes.

Accessories :-

* These are ideal to make maximum use of a flat screen LCD TV. They will add about 2" to the depth of the set. Wall mounts that tilt for viewing anywhere in a room are also available as are articulating mounts which mean you can push the set flush to the wall when you are not using it.

* It is worth knowing that table stands need to be suitable for the particular make of LCD TV you buy. If a stand is not included with the set check carefully before you buy one that it will do the job.

HDTV Buying Guide

What is HDTV?
High-Definition TV (HDTV) is the most exciting thing to happen to television since black and white turned to colour. The main fact you need to know is that HDTV pictures contain four times as much picture definition as the standard TV pictures we watch currently.

What's the difference between analogue, digital, and HDTV
Analogue TV: An analogue television is capable only of displaying standard definition images as currently found on terrestrial, cable, Free view and satellite broadcasts. Analogue televisions cannot display High-Definition pictures.

Digital TV: A digital television operates using digital rather than analogue signals and broadcasts in true widescreen format. Digital televisions can display HD pictures, though not to their true resolution.

HDTV: A High-Definition television can display analogue, digital and true High-Definition TV signals, although there are a variety of important factors to consider when picking the best television for your needs. The main areas to look at are:

Key features of HDTV's

* All digital displays make their pictures up using pixels, where the more pixels a screen has, the better and the image. This is called the screen resolution and it is well worth having a basic knowledge of the resolution formats if you want to make the most informed choice when purchasing your new HD kit.

* The two formats for High-Definition are 720p and 1080i. The 1080i format contains 1080 lines of image information, which is produced using the interlaced (hence the 'i') system. This means the pictures on your television are produced in two separate 'sweeps', with the odd lines (1, 3, 5, 7 etc) created during the first sweep and the even lines (2, 4, 6, 8 etc) created during the second. The sweeps are so quick, however, that the human eye sees only one complete image.

* The 720p format, while having fewer lines of image information, uses progressive-scan technology (hence the 'p'), where all the lines are created at once, as opposed to two separate sweeps. This ensures an exceptionally smooth image, which is often preferable to 1080i for fast-moving footage (again, such as football).

* But as technology improves and with the launch of High-Definition (which is shot in widescreen format), the only real choice is to opt for a widescreen TV when making your next purchase. Almost all large (28-inch and above) screens are now only available in widescreen format though, making it an easy decision to make!

* Where the image on your screen is created by two 'sweeps', where the odd lines are produced in the first sweep and the even lines in the second sweep, with the two sweeps interlaced to create one picture. One of the key High-Definition formats, 1080i, uses interlacing technology.

AdSense

AdSense is an ad serving program run by Google. Website owners can enroll in this program to enable text, image and, more recently, video advertisements on their sites. These ads are administered by Google and generate revenue on either a per-click or per-thousand-impressions basis. Google is also currently beta-testing a cost-per-action based service.

Google utilizes its search technology to serve ads based on website content, the user's geographical location, and other factors. Those wanting to advertise with Google's targeted ad system may sign up through AdWords. AdSense has become a popular method of placing advertising on a website because the ads are less intrusive than most banners, and the content of the ads is often relevant to the website.

It currently uses JavaScript code to incorporate the advertisements into a participating site. If it is included on a site which has not yet been crawled by the Mediabot, it will temporarily display advertisements for charitable causes known as public service announcements (PSAs). (Note that the Mediabot is a separate crawler from the Googlebot that maintains Google's search index.)

Many sites use AdSense to monetize their content and some webmasters work hard to maximize their own AdSense income. They do this in three ways:

1. They use a wide range of traffic generating techniques including but not limited to online advertising.
2. They build valuable content on their sites; content which attracts AdSense ads and which pay out the most when they get clicked.
3. They use copy on their websites that encourage clicks on ads. Note that Google prohibits people from using phrases like "Click on my AdSense ads" to increase click rates. Phrases accepted are "Sponsored Links" and "Advertisements".

The source of all AdSense income is the AdWords program which in turn has a complex pricing model based on a Vickrey second price auction, in that it commands an advertiser to submit a sealed bid (not observable by competitors). Additionally, for any given click received, advertisers only pay one bid increment above the second-highest bid.

History

AdSense was developed by Oingo, a small search engine company based in Santa Monica founded in 1998. Oingo focused on semantic searches rather than brute force string searches. Oingo changed its name to Applied Semantics, which was then bought by Google in April 2003, to replace a similar system being developed in house. [1]

AdSense for feeds

In May 2005, Google unveiled AdSense for feeds, a version of AdSense that runs on RSS and Atom feeds that have more than 100 active subscribers. According to the Official Google Blog, "advertisers have their ads placed in the most appropriate feed articles; publishers are paid for their original content; readers see relevant advertising — and in the long run, more quality feeds to choose from".

AdSense for feeds works by inserting images into a feed. When the image is displayed by the reader/browser, Google writes the ad content into the image that it returns. The ad content is chosen based on the content of the feed surrounding the image. When the user clicks the image, he or she is redirected to the advertiser's site in the same way as regular AdSense ads.

AdSense for search

A companion to the regular AdSense program, AdSense for search lets website owners place Google search boxes on their pages. When a user searches the web or the site with the search box, Google shares any ad revenue it makes from those searches with the site owner. However, only if the ads on the page are clicked, the publisher is paid. Adsense does not pay publishers for mere searches.

How AdSense works

Each time a visitor visits a page with an AdSense tag, a piece of JavaScript writes an iframe tag, whose src attribute includes the URL of the page. Google's servers use a cache of the page for the URL or the keywords in the URL itself to determine a set of high-value keywords. (Some of the details are described in the AdSense patent.) If keywords have been cached already, ads are served for those keywords based on the AdWords bidding system.

Abuse

Some webmasters create sites tailored to lure searchers from Google and other engines onto their AdSense to make money from clicks. These "zombie" sites often contain nothing but a large amount of interconnected, automated content (e.g. a directory with content from the Open Directory Project). Possibly the most popular form of such "AdSense farms" are splogs ("spam blogs"), which are centered around known high-paying keywords. Also many sites use free content from other web sites, such as Wikipedia, to attract visitors. These and related approaches are considered to be search engine spam and can be reported to Google.

There have also been reports of Trojans engineered to produce fake Google ads that are formatted to look like legitimate ones. The Trojan Horse apparently downloads itself onto an unsuspecting computer through a web page and then replaces the original ads with its own set of malicious ads. ^[1]

Criticism

Due to concerns about click fraud, Google AdSense has been criticized by some SEO firms as a large source of what Google calls "invalid clicks". Some disabled publishers have complained that the process is not transparent or accountable. ^[2]

To help prevent click fraud, publishers can choose from a number of click tracking programs. These programs will display detailed information about the visitors who click on the AdSense pages. Publishers can use that data to determine if they've been a victim of click fraud or not. There seems to be many such commercial scripts available. An open-source alternative is AdLogger.

Google has also come under fire for not doing enough to combat the misuse of trademarks. Since 2004, Google had stopped prohibiting advertisers from bidding on any keyword, including trademarked terms. ^[3]
